The nut is an option. You can go shouldered if you want. The bolt head may need to be changed if it is not already a Magnum. The Firing pin protrusion will need to be reset. The bolt heads are rarely the same and the magnum is 1/16th longer on the lugs than the standard.

Good luck
The receiver doesn't have the bolt, magazine, it's basically stripped. I'm starting from scratch, so it's a blank canvas ready for a build.

Any more ideas I'm all ears. :)
